[Quoth]

2016, so seriously obsolete as you'd expect from the low 256 x 256.

Also a stupid choice for:
Anything other than a product label.
Any new product / retail label tag as there are far better ones.

Absolutely the worst eink panel I've seen as only 1bit (black or white) and only 256x 256. Only good to show QR codes.

This is a toy at about x20 the price you'd expect to pay for it. OLED is the 1st choice for opaque goggle panels and LCD if you don't care about the extra depth needed or want translucent view, but AR really needs projection and clear "glasses".

Also 512 x 512 with greyscale to anti-alias would be a bare minimum resolution, but 600 x 800 would be better. I'd go for a minimum of 1920 px wide and 1440 high using OLED if I was designing immersive reading goggles. I'd design it with micro HDMI in, USB-C with Video, Miracast/screencast, 3.5mm stereo jack in (with option for composite video), composite & Y/C, firewire in and earphones. Electronics in a small box with the power cell and all I/O with spring loaded cable to display/earphones for movement and to make headset as light as possible. You'd be able to use it then as a display/earphones on a phone, tablet, setbox, computer, portable DVD player, VHS, camera, camcorder (analogue or digital). Handy for long airplane flights. You'd want sound to be mix in ambient, noise cancelling or regular. Displays to simply duplicate if no stereoscopic source. Maybe option for 2x webcams (add a 2nd USB) to do simple AR.


Edit:
The last complete do everything gadget I designed was in 2007. The bench version had 1024 x 768 touch screen and the true portable demo used 2 x LiPoly and only 320 x 240 touch screen. But that was FIFTEEN years ago. The year the first iPhone launched. A year before Android. Also it was only an internal "proof of concept" for an early 4G system. It even used a PCMCIA card slot for a prototype modem made for a laptop. Debian, Ice Window Manager OR QT phone Edition GUI. VOIP with geographic number, Thunderbird, Firefox, media player. Separate USB host (A) & client (mini-USB), full size SD card slot, stereo headphone, built in mono speaker, stereo line in and mic in (3 x 3.5mm jacks). Coax plug to charge for the 15 minute run time. It was never ever intended as a product but to demo what the mobile network could do. It used a 4G system you probably never heard of because LTE and Qualcomm didn't just kill Wimax 4G, but all the other post 3G mobile systems.
